My ASP.NET application requires me to create various temporary tables in TEMPDB. There is a problem that I am facing for which I need a solution badly.
There is a class which creates a temporary table in TEMPDB.
There is another class which needs to use this temporary table.
The issue is once the first class is exited or the connection to the database is closed, the temporary table vanishes and there is a runtime error thrown by the second class as it cannot find the temporary table.
Is there any way I can persist the tables in TEMPDB for subsequent operations?
Any help or clue in this regard would be a major help
"tempdb is skipped. You cannot run a query that requires tempdb"?
We're running a .Net web application with a SQL Server 2000 backend, and we get the error intermittently. Restarting the SQL Server service seems to fix it, as it causes tempdb to be rebuilt, but this isn't a long term solution. Any direction or hints would be greatly appreciated. Thanks! - Mike
Is it a good thing to do? what are the cons? Are there any risks? (this isan ISP database running 24 hrs) I have sql 6.5 on Win NT with 256 MB Ram (64MB reserved for SQL Server). tempdb size is 10 MB. Currently i'mexperiencing slow response for large queries and sometimes users haveproblems logging on the internet (authentication stops).thx
Being new to SQL server I would like some information regarding the tempdb database.
I user SQL Server 2000.
At present I appear to be backing up my tempdb but it has been failing since way back. It gives me this error when trying to bakup the database:
Executed as user: NT AUTHORITYSYSTEM. Backup and restore operations are not allowed on database tempdb. [SQLSTATE 42000] (Error 3147) BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.
Can someone give me a basic grounding as to what the tempdb is used for and should I back it up or not?
Everything I've ever heard or seen says not to put tempDB in RAM, citing reasons of negligible benefit or even worse performance as it steals memory from SQL's cache memory.
My issue is I need to take anywhere from 500 to 3000 records (games played) in a batch every five minutes from a table, ordered by game id. There's no guarantee of sequential order to how the records are inserted, so I need to do an ORDER BY in my query. I also do a stored procedure for ranking that requires an ORDER BY.
The performance difference between the two is staggering. 1000 records with a 200 mb tempdb database (not in RAM) takes about 300 seconds. With a 16 MB tempdb database IN ram, it takes just under 127 seconds. Only problem? I'm constantly getting, after a few batches have run, "out of space in syslogs for tempdb ram messages. "
Is there a way to net such performance from tempdb without putting it in RAM, and if not, is there a way to explicity clear out tempdb. Thanks for any help.
I am trying to configure a 6.5 server to set the tempdb to run off disk. I reset the tempdb in ram = 0 in the configuration, and restarted the service, but it left it as running in ram, with 0 configured. I then rebooted the server, and it still left the tempdb in ram. Any ideas?
Hi! How can I change the default physical location of the tempdb. In the setup , you will only be prompted the directory for the software and the directory for the data.
In sq6.5, you can move the tempdb out of the master device by putting it to ram and changing the default device. But in sql7.0 it is separated from the master but the physical device is located the same as the other data files.
I read an article on this site by Michael Hotek re "Basic SQL Server 6.5 Configuration Options". In the paragraph about TempDB he says that you should always avoid using Temp tables in stored procs. I use this feature a lot when trying to do "not in" type queries (I filter out a portion of a larger table and then use the "not in" on the temp table rather than the entire table.) Is there a better way to run a Not in query. I have the table well indexed (i think) but it seems to do a full table scan if I use the entire table.
Error : 933, Severity: 22, State: 1 Logical page 258 of the log encountered while retrieving highest timestamp in database 'tempdb' is not the last page of the log and we are not currently recovering that database.
I use sqlserver -T4022 to start my SQL Server since it will not start with out it. When I start sqlserver without the option, it tells me that
Error : 615, Severity: 21, State: 1 Unable to find database table id = 2, name = 'tempdb'.
I have a problem with Tempdb database on SQL 6.5 server.....when i create a temporary table, i block other users in other databases. Actually i run a stored procedure which creates a temporary table and then the procedure insets some values of a table from my test database. When the spored procedure is executed, users in other databases also get blocked and no new user will be allowd to log on to the server. When i check as to what the other users are executing, i find that they are also creting or droping a temp table. So i will have to either kill my SP or let it finish and continue blocking other users.
As of now, i am not able to find a reason for that and i try to run the Stored procedure in offpeak hrs.
I have not played around much with Temp tables in SQL 6.5. Pl do suggest me as to what to do....
Some details you would be interested on :
Server - SQL Server 6.5 Front End - Great Plains Size of Tempdb - Data Space Available( It says shared with data) database_name database_size unallocated space ------------------------------ ------------------ ------------------ tempdb 1502.00 MB -6301.82 MB
Our Tempdb.mdf file is 11 gigs. I have tried several things to shrink this but with no luck. Does anybody have a suggestion on how I can free up that space. I have tried to re-start Sql but that didn't do anything. I thought that there was a bug, if the files got above 4 gig that sql wouldn't clear them, but I could be wrong
I thought I could detach it, and attach a new file, but makes me nervous without knowing if thatís correct.
I am trying to get some information about tempdb database. I've tried BOL but I couldn't find a whole lot of info. I am trying to find out what size should tempdb be to not to cause problems. Also, I am trying to shrink tempdb by using shrink database option in EM, but it only shrinks the tempdb transaction log not the datafile, and I don't know why it is happening.
I need to move tempdb to another drive,also increase the size.Largest database is 15GB.Can anyone suggest the size and also the exact commands to move.Do I need to backup the databases before I do this task?If SP1 is not installed,will it be o.k for me for this tempdb problem.If we have a larger tempdb like 4GB,will it effect anything?...Urgent!!
TEMPDB in one of our production servers does not clear up so every three to four weeks I have to restart NT. Nothing like this happens on any of the other three servers. Does anybody know where I should look at to correct the problem. I sure would appreciate it. Thanks Shashu
My company uses a CRM application on SQL Server. We recently performed some upgrades of the CRM application that required us to move from SQL 6.5 to SQL 7.0. In our stored procedures we make extensive use of temporary tables. Our performance has slowed a lot since the upgrade. When we used SQL 6.5 we placed the TEMPDB in RAM to increase performance. According to Microsoft, this option is no longer available because of SQL's self-tuning ability. It would seem obvious that having the TEMPDB on disk is going to be much slower than having it in memory. I was wondering if anyone else is in the same boat, and what you did to speed up SQL Server?
I have never done this before and thought I would ask. Is it possible to detach the tempdb database, move it to another drive or partition, and then re-attach it? What would be the downside or side-affects to doing such a thing?
THis is sql server 6.5 question. I have tempdb data device size default 2 MB, which has completely filled up. I am trying to expand data device to it. I created new device tempdb_data_ext (250 MB) and tried to expand tempdb data device. But everytime I do it, it ends up adding space to tempdb log device. How can I expand tempdb data device?
Hi All if temdb grows and use all the disk space and then after log backup or other clean up process its size got reduced but it is still holding the space it was grown upto. In this case what would be ideal to do restart server/services or is it possible to reduce the space alocated to tempdb through properties.
So i've been delegated to be a SQL Server DBA now (which I am perfectly content with), but im running into some issues and I am not sure how to proceed.
To make a long story short:
-installed a new server with SQL Server 2005 SP1. Has two databases on it. -(2) arrays: 1st array is RAID 1 with some of the database and t-logs on it (I know..working to fix): 2nd array I just moved the tempdb.mdf file and tempdb.ldf files over this morning.
I was getting horrible I/O performance (to be expected) which prompted me to put in some more drives and move the tempdb files. This helped a bit, but now I am noticing some very funky things.
Over the last hour, i have seen my tempdb.mdf file grow from 10mb to almost 90gigs. I've been watching the performance on this machine, and the array with the tempdb is really seeing a lot of writes to it.
I am very very new to SQL server. Does anyone have some suggestions on profiiling and tracing I can do to see what is going on? Something in the Query analyzer?
I really appreciate it very much. This is new territory for me.
For a variety of reasons, the C drive on our Production Server is low on disk space. When we ordered the server it came installed with SQL Server 2005 and they defaulted the System databases to the C drive. All our client dbs are on the F drive. The tempdb database gets fairly large every day and consumes a large portion of what is left of the C drive. Every evening, after work hours, I have to stop SQL Server, delete the tempdb.mdf and ldf files and restart. Is there a way to move the default location of the tempdb files to the F drive? I do not want to repartition the hard drive or uninstall and reinstall SQL Server.
